    Urgent!! MMSC returning M-Send-cnf with status set as "Invalid content; Plz try again

    Hi,

    I am trying to send M-Send-Req PDU to an MMSC. But it returns M-send-cnf with "Invalid Content; Plz try again" status set as 0x83.

    I have sent my M-Send-req PDU as follows...

    0x8c, 0x80, 0x98, 0x4d, 0x73, 0x67, 0x54, 0x49, 0x44, 0x31, 0x32, 0x33, 0x34, 0x0, 0x8d, 0x90, 0x97, 0x39, 0x31, 0x34, 0x36, 0x36, 0x33, 0x37, 0x32, 0x0, 0x8a, 0x83, 0x8f, 0x81, 0x94, 0x81, 0x86, 0x81, 0x90, 0x81, 0x84, 0xa3, 0x1, 0x1, 0x15, 0x83, 0x77, 0x72, 0x69, 0x74, 0x65, 0x20, 0x79, 0x6f, 0x75, 0x72, 0x20, 0x74, 0x65, 0x78, 0x74, 0x20, 0x68, 0x65, 0x72, 0x65, 0x00

    The PDU can be decoded as follows.....

    0x8c, 0x80, -- Msg Type M-Send-req

    0x98, 0x4d, 0x73, 0x67, 0x54, 0x49, 0x44, 0x31, 0x32, 0x33, 0x34, 0x0, -- TID-- MsgTID1234

    0x8d, 0x90, -- MMS Version 1.0

    0x97, 0x39, 0x31, 0x34, 0x36, 0x36, 0x33, 0x37, 0x32, 0x0, -- To -- 91466372

    0x8a, 0x83, -- Msg Class -- Auto

    0x8f, 0x81, -- Priority -- Normal

    0x94, 0x81, -- Sender Visibility -- Show

    0x86, 0x81, -- Delivery-Report -- No

    0x90, 0x81, -- Read Reply -- No

    0x84, 0xa3, -- Content-type -- Multipart.Mixed

    0x1, -- number of components

    Component starts
    =============

    0x1, -- length content-type plus other headers

    0x15, -- Length of data

    0x83, -- Content Type text/plain

    0x77, 0x72, 0x69, 0x74, 0x65, 0x20, 0x79, 0x6f, 0x75, 0x72, 0x20, 0x74, 0x65, 0x78, 0x74, 0x20, 0x68, 0x65, 0x72, 0x65, 0x00 -- DATA--- Equivalent text is "Write your text here"


    I am not able to find any problem here...
    But the MMSC says "Invalid content" with status header set as 0x83. Am I missing some header here? like "Accept Charset"... etc...
    OR
    Do i have to prepend "+" before the phone number? (but this shd not be a big problem.. i feel)

    Can anybody plz let me know if some changes to be made to this.

    Thanx in advance
    Murali
